Raisbeck Unveils Composite 5-Blade Swept Propeller for King Air 200s

Just in time for NBAA in Las Vegas, Raisbeck Engineering, Inc., plans to debut a new composite 5-blade swept propeller for the Beechcraft King Air 200 series aircraft at its booth (C-11443). The company has already begun taking orders for the new propeller.

Designed by Hartzell Propeller specifically for King Air 200, B200, and B200GT aircraft, the new propeller was STC’d by Raisbeck Engineering for a 30% reduction in noise throughout the aircraft. With over 30 years of experience in the design, manufacturing, and certification of structural composite propellers, Hartzell and Raisbeck have a long-standing relationship in developing swept blade technology for the entire King Air line.

Constructed of structural carbon fiber composite with nickel cobalt leading edges to protect against foreign object damage, the new 5-blade propellers optimize airfoil efficiency allowing for a larger 96-inch diameter propeller with less blade tip noise. The propeller also features unlimited blade life, thereby lowering maintenance and overhaul costs.

King Air operators who chose the 5-blade propeller will enjoy an average total weight savings of 48 pounds versus OEM installed propellers, a 16.5 percent performance boost in runway acceleration, a 48 % more effective prop in reverse and 25.8% performance improvement during engine-out climb scenarios with flaps up. The company also offers King Air 200 aircraft owners and operators the option of an aluminum 4-blade swept propeller.
